Meaning

noun any of numerous varieties of Narcissus plants having showy often yellow flowers with a trumpet-shaped central crown

originVariant of Middle English affodill (“ramson”), from Medieval Latin affodillus, from Latin asphodelus, from Ancient Greek ἀσφόδελος (asphódelos), of Pre-Greek origin. The initial d- is perhaps from merging of the article in Dutch de affodil, the Netherlands being a source for bulbs (compare adder, apron, newt, nickname, orange and umpire for this rebracketing process). Doublet of asphodel.
